OVERVIEW

Taking care all aspects of a sprinter’s needs, Racing Spec. 5.2 is the perfect weapon for winning bunch sprints.

Racing Spec 5.2 is built with solely one objective in mind – sprint victories. Refined to perfection, it has significantly improved in terms of aerodynamics, lateral and torsional stiffness, lightness, and riding comfort from its first-generation predecessor.

The newly designed 25 mm wide aero profile rim combining with TORZC second-generation Ultra Smooth Carbon Fiber Moulding Technology has created a highly responsive 52 mm depth wheel with excellent aerodynamic efficiency at high speed.

Since 2018, all Racing Spec wheels have introduced with the new carbon Diamond Polishing TreatmentTM on the braking surface, which provides supreme braking performance in both wet and dry conditions.

  • Inherited the rolling smoothness from its previous generation predecessor.
  • Increased overall stiffness by 15% while the net rim weight reduced by 8%.
  • Improved stability in aggressive cornering, overall handling, and comfort with the new 25mm wide carbon rim design.
